Recently Blizzard added a lot of great new music tracks to the game, but some of my personal favorites happen to be the older, traditional compositions if you will. I have actually found myself missing the old Inn music, despite getting the new tracks stuck playing in my head (as is happening at this very moment, as a matter of fact.) As much as I am in love with the Lament of the Highborne, I find the music in Auberdine to be equally stirring.
Perhaps it's the simple fact that I know the original music so well. My characters grew up with that music, and it seems strange to walk into a place and hear something unfamiliar. I suppose music makes me more nostalgic than I realized.
